### Abstract

The chiral phase transition at finite temperature is studied by using the Schwinger-Dyson equation in the dual Ginzburg-Landau theory, in which the dual Higgs mechanism plays an essential role on both the color confinement and the spontaneous chiral-symmetry breaking. At zero temperature, the quark condensate is strongly correlated with the string tension, which is generated by QCD-monopole condensation, as 〈q̄q〉^{1/3} ^{∝}_{∼} √σ. In order to solve the finite-temperature Schwinger-Dyson equation numerically, we provide a new ansatz for the quark self-energy in the imaginary-time formalism. The recovery of the chiral symmetry is found at high temperature; T_{c} ∼ 100 MeV with realistic parameters. We find also a strong correlation between the critical temperature T_{c} of the chiral symmetry restoration and the strength of the string tension.
